To all whom it may concern.

Be it known that I, FRANcrs H. RICHARDS,

a citizen of the United States, residing at Hartford, in the county ofHartford and State of Connecticut, have invented certain new and usefulImprovements in Carvmg-Machines, of which the following is aspecification.

My present invention relates to machines:

for carving wood, moldings or the like, and

more particularly pertains to this class of carving machines in whichthe feed of the stock is continuous and the cutting elements 1 produce apractical, efficient machine of the character above set forth which willbe capable of continued use with a minimum amount of wear and vibration.

My present invention consists in the organization and novel combinationsof elements hereinafter more fully set forth and claimed.

My invention is illustrated in one embodiment of the same in theaccompanying drawings, in which a carving machine is shown in Figure 1as a front elevational view with the front wall removed to more closelyshow the; parts; Fig. 2, a right side elevation showing. the nearestside wall removed; Fig. 3, a plan view showing the stock in position tobe op. erated upon; Fig. 4, a plan view of the interior of the machine,the top portions of the frame A being removed or broken away to show thelower portion of said mechanism, the carriage being shown in horizontalcross-section through the perimetral groove therein; Fig. 5 shows adetail in perspective of the tool-carrying carriage; Fig. 6 is avertical section in perspectlve showlng the mechanism of the feed rollsand rotary cutter somewhat broken away Fig. 7 shows a detail end view ofthe feed mechanism, Fig. 8 shows a detail plan view of same; Figs. 9, 10and 11 show time charts of the movements of the carriage and stock andtheir operating mechanism, and Fig. 12 shows a diagrammatic View ofapiece of stock and the rela- -from the top plate 13.

tive movements of the cutters to the stock during the cycle of themachine.

Referring to the drawings, the machine is mounted and assembled upon abox-like frame A. A horizontal driving shaft 2 is mounted longitudinallyof the frame A in bearings 3 in the walls of said frameA. The drivingshaft 2 extends through one wall of the frame A and is provided withoutsaid frame upon a projecting portion with a driv ing pulley 4. Thedriving shaft 2 is restricted against longitudinal movement by the hubof the driving pulley 4 and a collar 5 on said shaft abutting theopposite sides 0 one of the bearings 3.

Referring to Fig. 2, the driving shaft 2 is provided upon that portionlying entirely within the frame A, beginning at the left with aneccentric 6, with a cam-groove wheel 7 and a spiral gear 8, all mountedfast upon said sh aft 2. A spiral gear 9 meshing with the spiral gear 8is mounted upon the shaft 10, which shaft 10, is journaled in a bearing11 projecting from one of the walls of the frame A and a bearing 12 in atop plate 13 of the frame A. The shaft 10 is restricted againstlongitudinal movement by the abutment of spiral gear 9 with the bearing11 and the abutment of a collar 14 mounted upon said sh aft 1.0 with theopposite side of the bearing 12. The shaft 10 projects through the bearing 12 and the top plate 13 of the frame A and is provided upon itsprojecting end with a spira gear 15.

The driving shaft 2 is mounted at about the central portion of the frameA and the shaft 10 is inclined in such a manner that its upper end willmore nearly approach one side'of the frame A. This shaft 10 is geared tomake one revolution to eight revolutions of the driving shaft 2. i

A spiral gear 16 meshing with the spiral gear 15 is mounted fast upon ahorizontal shaft 17 which is monted longitudinally of the frame A inbearings 18 18 upstanding The shaft 17 is re stricted againstlongitudinal movement by the abutment of the hubs of two spiral gears 19and 20 against the inner faces of the bearings 18 18. The spiral gear 16is geared with the spiral gear 15 to produce a ratio of one to onebetween the shafts 10 and 17.

A shaft 21 is mounted directly beneath the shaft 17 and at right anglesthereto in the plane of rotation of the gear 19 in a bearing 22upstanding from the top plate 13 of the frame A, and a bearing 23 in anupstanding flange 24 of the said top plate 13. A spiral gear 25 ismounted fast on the shaft 21 and meshes with the spiral gear 19 on theshaft 17 in the ratio of one to one. A shaft 26 is mounted directlybeneath the shaft 17 and at right angles thereto in the plane ofrotation of the gear 20 in a bearing 27 from the top plate 13 of theframe A and a bearing 28 in an upstanding flange 24 of the said topplate 13.

A spiral gear 29 is mounted fast on the shaft 17 intermediate the spiralgears 19 and 20 and meshes with a spiral gear 30 fast on a horizontalshaft 31 mounted directly above and at right angles to the shaft 17 inthe plane of rotation of said gear 29 in a bearing 32 upstanding fromthe top plate 13 of the frame A and a bearing 33 upstanding from theflange 24 of said top plate 13. A stock guide 34 is secured to theflange 24 by screws 35, said stock guide being parallel with the shaft17.

The shafts 21 and 26 project through the bearings 23 and through theflange 24 and are provided upon their projecting portions with feedrolls 36 and 37 of equal diameter, which feed rolls are disposed withinhollows 37 and 38 in the stock guide and their peripheries projectslightly above the floor of said stock guide and may be provided withroughened surfaces or gripping teeth.

The shaft 31 projects through the bearing 33 and is provided upon itsprojecting portion with a rotary cutter chuck 39 carrying peripherallydirected tools 40 which will be inives of suitable formation securedthereto. That portion of the cutter chuck 39 carrying the tools 40overhangs the stock guide 34 in such a manner that the tools 40 willengage and incise stock lying within said stock guide.

A shaft 41 is mounted transversely of the frame A in bearings 42upstanding from the top plate 13 of the frame A and a frame 43 ispivoted. thereon and carries a shaft 44 which overhangs the stock guide34 and carries upon its overhanging portion a presser roll 45 which isadapted to press upon stock lying in the stock guide 34 directly abovethe feed roll 36. A spring 50 secured to said frame 43 and also to thetop plate 13 maintains a downward pressure upon said frame 43 whichpresses the presser roll 45 upon the stock and insures a closeengagement of the feed roll 36 with the stock.

A shaft 51 is mounted transversely of the frame A in bearings 52upstanding from the top-plate 13 of the frame A and a frame 53 ispivoted thereon and carries a shaft 54 which overhangs the stock guide34 and carries upon its overhanging portion a presser roll 55 which isadapted to press upon stock lying in the stock guide 34 directly abovethe feed roll 37. A spring 56 secured to said frame 53 and also to thetop plate 13 maintains a operation of the machine.

downward pressure upon said frame 53 which presses the presserroll 55upon the stock and insures a close engagement of the feed roll 37 withthe stock.

The operation of this mechanism is as follows: When the driving shaft 2is rotated the shaft 10 is driven therefrom one revolution to eight ofsaid driving shaft 2, and the shaft 17 is driven from the shaft 10 at anequal speed therewith, that is, at one-eighth of the speed of thedriving shaft 2. The shafts 21 and 26, and consequently the feed rolls36 and 37, are driven in the same direction from the shaft 17 at thesame speed therewith, that is, one revolution to eight of the drivingshaft 2, and as the feed rolls 36 and 37 are of the same diameter stock(shown at 46) lying in the stock guide 34 will be fed along at anuniform velocity, the presser rolls 45 and 55 pressing the stock intoactive engagement with the feed rolls 36 and Y 37. The shaft 31, andconsequently the rotary cutter chuck 39 carrying the tools 40, is gearedwith the shaft 17 to rotate in the opposite direction and is given thesame speed as the shafts 21 and 26 but in the opposite directionthereto. The active periphery of the rotary cutter is equal to that ofthe feed rolls and as the rotary cutter is disposed above the stock androtated in the opposite direction it will roll along the top face of thestock as the stock is fed uniformly by the feed rolls and incise bymeans of the tools 40the stock. The rotary cutter chuck 39 carriessixteen tools and therefore makes sixteen incisions in the stock to eachrevolution of the shaft 31 or two incisions to one revolution of thedriving shaft 2. The tools 40 make sub stantially perpendicularincisions in the stock, and in the machine illustrated these incisionsare very short, which is the case with machines of this character forincising stock of the character for which this machine is designed. Asthe depth of these vertical incisions is not very great the rotarycutter is eminently satisfactory for the purpose and the arcual movementof the tools is not no-' ticeable in the finished product. In design inga practical machine for operating upon continuously fed stock the formof rotary cutter for making shallow incisions is preferred as theorganization of the mechanism for driving same is devoid ofreciprocating movement and the conse uent vibration accompanying thesame. n the organization shown the resistance offered to the rotarycutter is practically constant throughout the The remaining portion ofthe top of frame A is covered by a plate 57 secured to the frame A byscrews 58. The plate 57 is provided with a rectangular aperture 59 whichaperture when the plate 57 is removed from the frame A is open at oneside but when the plate 57 is secured to the frame A is closed by ahorizontal flange portion of the stock guide casting 43. This horizontalportion of the stock guide casting and the plate 57 form a continuoustable with a rectangular aperture therein. A car riage 60 having aperimetrically-disposed groove 61 is adapted to be inserted in theaperture 59 of the plate 57 while said plate is removed from the frame Athe flanges 62 forming the walls of the groove 61 of the carriage 60grasping the plate 57 about the aperture 59 and when said plate 57 isput in place upon the frame A the said flanges 62 will also grasp theedge of the horizontal flange portion of the stock guide 34. the base ofthe groove 6]. is much. smaller than the aperture 59 and may thereforebe moved about within said aperture both longitudinally of the frame Aand transversely thereof, while the flanges 62 are of much greaterdiameter than the aperture 59 and will not uncover any portion of saidaperture I at any pomt 1n the movement within said.

aperture.

A horizontal shaft 63 is mounted longitudi nally of the frame Aapproximately beneath the aperture 59 in bearings 64 in walls of theframe A. The shaft 63 is restricted against longitudinal movement byfast collars 65 thereon abutting the inner surfaces of the bearing 64 Arocking beam 66 is mounted fast upon the shaft 63 and has two upwardlyprojecting arms 67 and 68, which arms 67 and 68 are bifurcated at theirupper extremities and embrace and are pivoted to the walls of saidguideways and control the The arms 67 and 68 by means of the blocks 69'and 7O1naintain the carriage 60 parallel to lateral movement of saidcarriage.

the stock guide 34 at all times but allow of the movement of saidcarriage independently longitudinally of the frame A. The beam 66 isprovided with a downwardly extending,

arm 7 3 which is connected with a connecting rod 74 which in turn isstrapped to the ec centric 6. Upon the rotation of the driving shaft 2the eccentric-6 through the connecting rod 74 imparts a rocking movementto the beam 66 which through the bearing block connections alreadydescribed imparts a re ciprocating movement to the carriage 60 towardand away from the stock guide 34, but owingto the slidable nature of thebearing blocks 69 and does not interfere with an independentlongitudinal movement of said carriage 60.

A rocking arm 75 is pivoted upon a stud 76 projecting from the side wallof the frame A and extends above said stud and is bifur- The carriage atl cated at its upper end, said'bifurcated por tion embracing and pivotedto a bearing block 77 adapted to slide transversely of the carriage 60in guideways 78 opening from the underside of said carriage. The bearingblock 77 closely engages the guideways 78 and controls the longitudinalmovement of the carriage 60 but is slidable transversely of saidcarriage in said guideways and admits of the transverse movement of saidcarriage which is imparted by the beam 66. All of the bearing blocks arevertically movable in the guideways to a slight extent to provide forthe arcual movement of the rocking members.

The rocking arm 75 is extended below the v stud 76 and is provided onits lower extremity with a laterally projecting stud 79 upon which aloose roller 80 is mounted. The loose roller 80 engages the groove inthe camgroove wheel 7 which groove is designed and formed to rock therocking arm 75 to impart a longitudinal movement to the carriage 60,which in the direction of the feed of the stock will be uniform andcorrespond to the move ment of the stock, that is, the carriage 60 willmove at the same speed as the stock. This movement with the stock, inthe machine illustrated, is designed to take place during a proximatelyfive-eighths of a revo- 5 lution o" the driving shaft 2 and the returnmovement in opposition to the direction of movement of the stock willtake place in the remaining three-eighths of a revolution of the drivingshaft 2.

A tool bed 81 is formed upon the upper surface of the carriage 60 uponwhich tool bed two tools 82,which are knives of suitable formation, aresecured by a tool clamp 83 and two setscrews 84 84 are mounted in anupstanding lug 85 from the tool carriage 60 and bear upon the rear endof the tool shanks to render a fine adjustment of the tools possible andto in a measure take the thrust upon said tools.

The eccentric 6, the cam-groove wheel 7 and the spiral gear 8 are setupon the shaft 2 and timed to produce a movement of the carriage 60 withthe moving stock in such a manner that the tools 82 upon the carriage 60will exactly register with two incisions previously made by the tools 40on the rotary cutter and during the movement of said car'- riage 60 withthe moving stock the carriage 60 will be carried toward the stockcausing the tools 82 to incise and chip out the ornamental figuredesired and clear the stock. It will be noted by reference to Fig. 12that the tools 82, the path of one of which is indicated by dottedlines, and sixteen consecutive positions of all of the parts during onerevolution of the driving shaft 2 are indicated by numerals from 1 to 16commencing at the position of the tool where it first engages the stockwill be carried upon the carriage 60 through one-sixteenth of arevolution of the driving shaft 2 and thereby allow momentum to beacquired by said carriage when the cutting stroke begins and will alsoleave the stock one-sixteenth of a revolution of the driving shaft 2before the carriage 60 is reversed or before the momentum is overcomeand movement in the op osite direction acquired. The tools 82 wil bestationary relatively of the stock during their cutting stroke andtherefore a clean long cut is made possible, while the return movementis relatively short. As illustrated, half of a revolution of the drivingshaft 2 is occupied in making the cut and withdrawing the tool, whileone-eighth is occupied in allowing the carriage 60 to acquire and toovercome its momentum and three-eighths is occupied in returning thecarriage 60 to its initial point to engage and incise the stock inregister with the two succeeding incisions previously made by the rotarycutter, and so on.

In Figs. 9, 10 and 11 the movements of the several moving agencies areillustrated by their curves, showing the timing of the parts andillustrating such timing in sixteen consecutive positions of the partsduring one revolution of the driving shaft 2. The time charts will bereadily understood.

It is obvious that various changes may be made in the construction anddetails of my device, and that the organization may be differentlyarranged to meet the exigencies of certain particular cases andvariously de signed stock to be operated upon, and that equivalentmechanical construction may be used in my organization without departingfrom the spirit and principle of my invention.

The commercial features of my invention will be readily understood byone skilled in the art, and the novel construction and arrangements willbe obvious to those having knowledge of this ty e of machines.

The importance 0 constructing and designing a machine which will bepractical, efficient, and capable of turning out a large amount offinished product in conjunction with such a construction as will renderthe machine capable of continued operation with a minimum ofdeterioration is obvious, and this has been the aim in the constructionand perfection of the present machine.
